Description

Technical Field

[0001] The present application relates to the field of limestone production equipment, and in particular to a chute material distribution device for limestone production. Background Art

[0002] In the limestone production process, the chute dividing device is a common equipment used to preliminarily screen and divide the raw materials containing impurities to improve production efficiency and product quality. Traditional chute dividing devices usually use chutes of fixed sizes and fixed filters. Although these devices can meet basic dividing needs, they have many limitations in practical applications.

[0003] For example, after placing limestone mixed with impurities on the filter, personnel can move the limestone to disperse it on the filter. Some improvers also use a pushing device to disperse the limestone so that the limestone can be screened out more thoroughly.

[0004] However, in the above-mentioned related technologies, as the limestone is screened, the height of the limestone will gradually decrease. When the limestone is lower than the pushing device, it is difficult for the pushing device to contact the limestone, thereby reducing the screening efficiency. Therefore, providing a material dividing device that can improve the screening efficiency is an urgent problem to be solved. Summary of the invention

[0005] In order to improve the screening efficiency, the present application provides a chute material dividing device for limestone production.

[0006] The present application provides a chute material distribution device for limestone production using the following technical solution: A chute material distribution device for limestone production, comprising a chute body and a filter assembly connected to the chute body; The chute body comprises: A length-adjustable side panel, wherein the length-adjustable side panel is perpendicular to the first direction, and two length-adjustable side panels are distributed in the first direction, and the extension direction of the length-adjustable side panels is parallel to the second direction; and Fixed-length side panels, in the second direction, two ends of the adjustable-length side panels are each correspondingly provided with a fixed-length side panel, and two sides of the fixed-length side panels are each correspondingly connected to one of the adjustable-length side panels; a material distribution trough is formed by the adjustable-length side panels and the fixed-length side panels, and the depth direction of the material distribution trough is parallel to the third direction; The filter assembly comprises: A filter element with filter holes, wherein two filter elements are sequentially distributed in the second direction, the ends of the two filter elements close to each other are sliding ends, and the ends of the two filter elements away from each other are hinged ends; The hinged end of the filter element is close to the fixed-length side plate and is rotatably connected to the fixed-length side plate via a first rotating shaft, wherein the first rotating shaft is parallel to the first direction; A sliding block is provided at the sliding end of the filter element. The filter element is rotatably connected to the sliding block via a second rotating shaft. The sliding block can slide along a third direction.

[0007] By adopting the above technical solution, after the limestone is poured onto the filter element, the slider is moved along the third direction. During this process, the fixed-length side plate will move in the second direction to adapt to the rotation of the filter element. During the rotation of the filter element, the limestone will be driven to roll along the filter element, so that the limestone can be screened more quickly, efficiently and thoroughly.

[0008] Optionally, the filter element includes: a frame, wherein the first rotating shaft and the second rotating shaft are both arranged on the frame; and A filter plate, on which the filter holes are formed, the filter plate is located in the frame, and the filter plate is slidably connected to the frame along the plate thickness direction of the filter plate itself; The filter assembly also includes an elastic member, one end of which is fixedly connected to the frame, and the other end is fixedly connected to the filter plate. When the elastic member is in a recoverable deformation state, it stores a force that drives the filter plate to move along the thickness direction of the filter plate itself.

[0009] By adopting the above technical solution, the sliding connection design of the filter plate in the frame allows the filter plate to move along its own plate thickness direction. Combined with the effect of the elastic member, the filter plate can be displaced when subjected to force. When the external force disappears, the elastic member can return to its original state and push the filter plate to reset, effectively preventing the filter holes from being blocked.

[0013] By adopting the above technical solution, the design of the length-adjustable side plate allows the chute body to flexibly adjust its width according to actual needs during use, thereby adapting to the rotation of the filter element; at the same time, the first linear drive component between the sliding plate and the fixed plate can accurately control the moving distance of the sliding plate, thereby ensuring the stability and reliability of the material distribution trough and improving the material distribution efficiency and accuracy.

[0014] Optionally, a second linear driving member is further included, wherein the second linear driving member is connected between the fixed plate and the slider to drive the slider to move along a third direction.

[0015] By adopting the above technical solution, the second linear drive member is connected between the fixed plate and the slider, which can accurately control the movement of the slider along the third direction; this allows the filter assembly to be flexibly adjusted between an upward inclined posture, a horizontal posture and a downward inclined posture, thereby effectively improving the screening efficiency and quality of the limestone.

[0016] Optionally, the second linear drive assembly is used to drive the slider to move along a third direction, so that the filter assembly can be adjusted between an upward tilted posture, a horizontal posture and a downward tilted posture; When the filter assembly is in an upward tilted posture, the filter element is tilted from the hinged end to the sliding end toward the top of the material distribution trough; When the filter assembly is in a horizontal position, the filter element is arranged perpendicular to the third direction; When the filter assembly is in a downwardly inclined posture, the filter element is inclined from the hinged end to the sliding end toward the bottom of the distribution trough.

[0017] By adopting the above technical solution, the limestone can be rolled back and forth between the sliding end and the hinged end of the filter element, so that the limestone can be screened more thoroughly.

[0018] Optionally, an upper discharge port is provided on the fixed-length side plate, and the upper discharge port is located on a side of the filter element close to the top of the distribution trough.

[0019] By adopting the above technical solution, when it is necessary to discharge impurities on the filter element, the impurities can be discharged through the upper discharge port without stopping the operation of the entire equipment, thereby improving the continuous operation capacity of the equipment.

[0020] Optionally, the fixed-length side plate is provided with a sealing plate for sealing the upper discharge port.

[0021] By adopting the above technical solution, when there is no need to discharge materials, the sealing plate can effectively block the upper discharge port to prevent material leakage during normal working.

[0022] Optionally, a material receiving assembly is also included, and the material receiving assembly includes: Racks; and A material receiving box, the material receiving box is fixedly connected to the frame, and in the third direction, one end of the material receiving box forms a material feed port, and the other end forms a material discharge port; The fixing plate is fixedly connected to the frame, and the bottom of the material distribution trough is located at the feeding port of the material receiving box.

[0023] By adopting the above technical solution, the fallen limestone can be easily collected through the material receiving box.
